A nurse is providing teaching to a client who has a depressive disorder and a new prescription for phenelzine. Which of the following foods should the nurse instruct the client to avoid?

A. Cottage cheese is low in tyramine and is safe for clients taking MAOIs like phenelzine. B. Spinach is also low in tyramine and does not interact with MAOIs. C. Smoked or aged fish, meats, and cheeses contain high levels of tyramine, which can cause a hypertensive crisis when combined with MAOIs such as phenelzine. Clients must strictly avoid aged, fermented, or smoked foods. D. Grapefruit interacts with certain other medications (e.g., statins, calcium channel blockers), but not typically with MAOIs.
